The Comprehensive Inner Magnetosphere-Ionosphere Model 

Fok, M. -C.; Buzulukova, N. Y.; Chen, S. -H.; Glocer, A.; Nagai, T.; Valek, P.; Perez, J. D. (2020-06-05)
Simulation studies of the Earth's radiation belts and ring current are very useful in understanding the acceleration, transport, and loss of energetic particles. Recently, the Comprehensive Ring Current Model (CRCM) and ...

Oxygen-hydrogen differentiated observations from TWINS: The 22 July 2009 storm 

Valek, P. W.; Goldstein, J.; McComas, D. J.; Ilie, R.; Buzulukova, N.; Fok, M. -C.; Perez, J. D. (2020-06-09)
The 22 July 2009 magnetic storm is the first significant storm during the emergence of the recent prolonged solar cycle minimum. This moderate storm (minimum Dst approximately -78 nT) has received a good deal of attention ...

TWINS stereoscopic imaging of multiple peaks in the ring current 

Perez, J. D.; Goldstein, J.; McComas, D. J.; Valek, P.; Buzulukova, N.; Fok, M. -C.; Singer, H. J. (2020-06-05)
Global, ion equatorial flux distributions and energy spectra are presented from stereoscopic Two Wide-Angle Imaging Neutral-Atom Spectrometers (TWINS) 1 and TWINS 2 energetic neutral atom (ENA) images for two time periods, ...
